Re: [FTC]: dual synchronized servos or geared up winch servo?

So maybe a block of rubber with holes punched into it would work?

We thought about this but the cables to the motors would be required to be longer than the maximum allowed cable length, plus probably not enough torque. The loader is out at the end of an arm that is attached to a linear lift.

We'll run some tests on the servos when they come in. May have to improvise a little.

Thanks!
